Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 774, here are decompositions:
- 5 + 769 = 774
- 13 + 761 = 774
- 17 + 757 = 774
- 23 + 751 = 774
- 31 + 743 = 774
- 41 + 733 = 774
- 47 + 727 = 774
- 73 + 701 = 774
Showing the first eight; more decompositions exist.
